Amazon Neptune announced support for openCypher , a popular query language for building applications with graph databases. Developers can now use openCypher with Amazon Neptune, giving them more choices to build or migrate graph applications to a highly available, secure, and fully managed graph database. Support for openCypher is compatible with our customers’ existing property graphs and developers can use both Apache TinkerPop Gremlin and openCypher queries within the same graph.

You can now launch RabbitMQ 3.8.17 brokers on Amazon MQ. This patch update to RabbitMQ contains several fixes and enhancements compared to the previously supported version, RabbitMQ 3.8.11.

Amazon S3 on Outposts now offers two larger storage tiers: 240 TB and 380 TB. These new storage tiers help you meet your needs for workloads with larger object storage requirements, and add to the existing options of: 26 TB, 48 TB, and 96 TB storage tiers.

Amazon EC2 Auto Scaling now lets you control which instances to terminate during a scale-in event by allowing you to provide a custom function that selects which instances to terminate. Previously, you could use one of the predefined termination policies to determine which instances Auto Scaling would terminate. (For example, the OldestLaunchTemplate termination policy would terminate instances in order of their launch template age, oldest first.) Now, you can provide a custom Lambda function that indicates which instances are safe to terminate on scale in. This feature is useful for stateful applications where you want to control which instances Auto Scaling terminates so that your application is not disrupted on scale in.

Today, AWS announces the general availability of AWS IoT SiteWise Edge, a feature of AWS IoT SiteWise that makes it easy for industrial customers to collect, organize, process, and monitor equipment data on-premises (i.e. at the edge). SiteWise Edge software enables factory operators to get visibility into their equipment data and make decisions that help improve equipment uptime, product quality, and process efficiency.

The Amazon DynamoDB Accelerator (DAX) SDK for Java 2.x is now available and is compatible with the AWS SDK for Java 2.x. You can build Java applications with accelerated access to DynamoDB and benefit from non-blocking I/O and other features of the latest AWS SDK for Java.

We are excited to announce the availability of smaller sized Amazon EC2 G4ad instances that deliver up to 40% better price performance over comparable GPU-based instances for graphics intensive applications such as virtual workstations and game streaming. Like the other G4ad instances, these new sizes are powered by AMD Radeon Pro V520 GPUs and second-generation AMD EPYC processors and are designed to be cost-effective for workloads that don’t need the high vCPU and system memory that current larger G4ad instance sizes offer providing the lowest cost GPU instance in the AWS Cloud.

Amazon Keyspaces (for Apache Cassandra), a scalable, highly available, and fully managed Apache Cassandra–compatible database service, now automatically optimizes client connections made through AWS PrivateLink to improve availability and read/write throughput.

Amazon Rekognition Custom Labels introduces a simplified on-boarding experience with the ability to explore images, labels, and datasets by one-click creation of example projects. Amazon Rekognition Custom Labels provides out of the box video tutorials, and example projects with hundreds of images for single-class classification, multi-class classification, object detection, and logo detection.

Lots of people have attempted to design and build fold-up 3d printers, many of which turn out quite compromised. Now I have seen the first that looks properly competent, and erects into something that prints well – I am guessing at least as well as ~£500 printers. It is a one-off by Kralyn3D, called the Positron, …
